Printer Crashes at the Beginning of a Print

3D Printing Asked by Rosalie W on December 1, 2020

I am converting an old Makerbot Replicator 2 to Marlin Firmware and everything works. The printer heats up, auto bed levels, and starts the print. However, after a couple minutes (usually after the 1st or 2nd layer), the printer crashes and stops. It does not continue printing and I have to restart it again. It crashed for every single print, I have not had any successful prints yet.

Here is a video showing the issue:

The camera was started right when the print started. After about 1.5 minutes, the printer crashes, and the lcd screen freezes.

Here are photos of a couple of prints that crashed:

I have all of my code here:

My models are sliced with Cura and printed in PLA.

I tried hotend temperatures of 200, 210, and 220 degrees. My print speed is around 50 or 60 mm/s.

Here is a sample sliced file that was used:

Thank you!

I see a couple likely culprits for a hardcrash like this

  • problems with the power supply. If the power supply does not provide enough voltage an/or current to the board, this can lead to a lockup of the board.
  • temperature issues of the board. If the board overheats, it could fail to execute properly, leading to abort. make sure that the board is not overheating.
  • faulty firmware. recompile your firmware and reflash it.
  • faulty board.

Few things to try,

Check G-Code - Verify that the slicer is not the problem, slice using some other program / make a new default profile and re-slice.

3D File - Also In parallel with the above point, I would get a standard test cube STL to start with. This will be a simple quick print to get a solid reference.

Voltages - Get a Multi-meter on the Regulated Voltage rails, 5V Rail, 12V rail / 24V rail. See if at the moment of crash a voltage rail collapse, the most likely one would be the microcontroller rail, but you may be able to see the problem somewhere else.

Current - If possible, measure the current draw of the printer either from the mains or after the AC/DC regulator. Its possible something is going horribly wrong and current limiting.

Serial Port - Possibly connect the printer to a PC via its serial port and open a com port. See if the printer spits out an error code at the time of crash?

End Stops - Double check that none of the End Stops are accidently being triggered (Although this should not crash the system, it might be part of the problem)

Verify Sensor Readings - Check all end stops, check the bed temperature readings, check the nozzle temperature reading. Maybe a sensor has failed and is causing the controller to crash out.
